Recycled and Secondary Materials Case Studies

The Case Studies Newsletter represents a joint effort by the Federal Highway Administration and various highway agencies to disseminate information on actual highway construction projects using recycled and secondary materials. These case studies will be of interest to highway engineers and materials engineers involved in the decision-making process regarding the use of recycled and secondary materials. In addition, construction personnel who will be called upon to build a project using a recycled or secondary material will find valuable information on the constructability of the material in a specific application. In effect, the case studies allow design and construction personnel a unique opportunity to learn from previous successes and mistakes on projects around the country.

The case studies are divided into several sections which: (1) describe the project, (2) outline the material used and the mix design, if appropriate, (3) provide an overview of the construction experiences, (4) evaluate the overall acceptability of the material in the specific application, and (5) offer "lessons learned" for future users of the recycled or secondary material. Additional information about the individual case studies can be obtained from the contacts listed at the end of each case study. In addition, there are appropriate "Links" to other Internet web sites where more general information could be obtained.

The Case Studies Newsletter is an evolving document that will be updated and expanded as future information on projects becomes available. Contact Timothy J. Lewis for any proposed additions to the newsletter.
